To all whom, it may concern:

Be it known that we, JAMES ONEILL BRUEN and WILLIAM AOKERMAN, citizens of the United States of America, residing at Ohanute, in the county of Neosho and State of Kansas, have invented new and useful Improvements in Apparatus for Extracting and Applying Well-Tubing, &c., of which the following is a specification.

This invention relates to an apparatus for extracting casings, tubing, and suckerrods from oil and gas .wells and also for lowering the same down into such Wells for appli cation therein.

The object of the invention is to provide an apparatus of this character which is simple of construction, powerful and eflicient in operation and use, comparatively inexpensive of production, and capable of being readily transported from place to place.

Another object is to provide a device of this character which may be operated by manual labor or horse or other power.

With these and other objects in view the invention consists of the novel construction, combination, and arrangement of parts hereinafter fully described and claimed, reference .being had to the accompanying drawings, in which Figure 1 is a front elevation of the device as arranged for use with the derrick elevated, a portion of the derrick being broken away on account of the confined space for illustration. Fig. 2 is a side elevation of the same, showing the elevated or operative position of the derrick in dotted lines and the lowered position thereof in full lines; and Fig. 3 is a side elevation showing the ratchet mechanism for manually operating the Windlass.

Referring now more particularly to the drawings, the numeral 1 denotes a suitablyconstructed truck-frame mounted on supporting-Wheels 2 and provided at the upper end thereof with a cross-bar 3. Rigidly attached to and extending from said truckframe are lower bracing-arms 4, reinforced from the truck-frame by bracing-irons 5 and pivotally attached, as indicated at 6, to the rear portions of foot-blocks 7. The footblocks 7 are spaced apart, as shown in Fig. 1, to form a base-support for the frame and derrick when the latter is elevated for operation. Upper bracing-arms 8 are connected at their rear ends, as indicated at 9, to the cross-bar 3 of the truck-frame and extend forwardly therefrom at an upward inclination and are connected at their forward or free ends bya transverse cross-bar 10, carrying a guide pulley or sheave 11. Standards or link-bars 12 support the forward ends of the upper brace-bars 8 and are pivoted at their upper ends to said bars, as shown at 13, and at their lower ends, as shown at 14, to the lower ends of the side arms 15 of a derrick 16. The lower ends of the said arms 15 of the derrick are fixed to a transverse shaft or axle 17 j ournaled in bearings 18 on the foot or base blocks 7, thus adapting the derrick to be swung to a substantially perpendicular position to rest against the cross-bar 10, as indicated in full lines in Fig. 1 and dotted lines in Fig. 2, or tobe turned down to rest upon the cross-bar 3 of the truck 1, as indicated in full lines in Fig. 2.

When the derrick is adjusted to an erect position for operation, it will be limited in its forward movement by said cross-bar 10, which will permit it to assume a forward inclination slightly beyond the vertical to permit the hoisting and lowering cable hanging pendent therefrom to project downward in advance of the supporting-frame and to be operated without interference therefrom.

The pivotal connection of the foot-blocks 7 with the lower bracing-arms 4 and the pivotal connections of the standards or link-arms 12 permit the derrick to swing freely from raised to lowered position Without throwing strain upon the parts of the supporting-frame. At a suitable distance above the axle 17 the side arms 15 of the derrick are'conneoted by a cross-bar 19 and at intervals above the same by other cross-bars 20, and the upper or free end of the derrick carries pulleys 21 and 22 and also loops or eyes 23, the latter being provided for the attachment of guide-chains to enable the derrick to be firmly braced against movement when elevated to operative position. The cross-bar 19 carries a ring or like fixture 24 for the attachment of the hoisting and lowering line when elevating and lowering the derrick, as hereinafter described.

A reel or Windlass 25 is mounted on the derrick in the space bounded by the lower portions of the side bars 15, axle 17, and cross-bar 19 and carries a set of drums 26 of varying diameter for the attachment of a Windlass-operating rope or cable. Said cord or cable may be attached to either one of the drums, according to the amount of power required to operate the Windlass, and draft-ani- IIO mals maybe attached to the cable, or the latter may be run out by any other suitable power to eifect the rotation of the Windlass. The Windlass also carries a brake-head or disk 27, adapted to be engaged by a brakeband 28, one end of said band being fixed to the cross-bar 19, while the opposite end thereof is connected to the crank end of an operating-lever 29, pivotally mounted upon the derrick, whereby the action of the windlass may be controlled and the same locked against movement when desired. To the shaft of the Windlass is connected a crankhandle 30, by which the Windlass may be operated by manual power to enable the hoisting and lowering line to be slacked or drawn taut for adjusting the grapples or extracting device mounted upon the free end of the line to enable said device to be conveniently connected with or disconnected from the part to be extracted from or lowered into the well. The head 27 is provided with ratchet-teeth 3 1, adapted to be engaged by a dog or pawl 32, pivotally connected with an operating-lever 33, pivoted to oscillate upon a bracket 34, fastened to one of the side bars 15 of the derrick. By oscillating this lever 33 the dog or pawl 32 may be brought into engagement with the ratchet-teeth 31 to intermittently rotate the Windlass for the purpose of raising the grappling or extracting device from the well and elevating the same to adjust it for more convenient application to a rod, tube, or casing-section to be elevated.

A hoisting and lowering line 35 is fixed and wound at one end around the Windlass 25 and then passes therefrom upward along the upper side of the derrick and is passed around the supporting-pulley 21, and thence continues when the derrick is in operative position downward over the guide-pulley 11, whence its .free end projects downward in advance of the base-blocks 7 for attachment to the grapple or extracting device. To elevate the derrick for operative position, the grapple or extracting device is detached from the free end of the line and the latter made fast to the ring or fixture 24, whereupon by turning the wheel 25 in a forward direction the line will swing the derrick forward until it comes in contact with the cross-bar 10. After the derrick has been stayed by the attachment of guide-chains to the eyes 23 the free end of the line is disconnected from the fixture 24 and the grapple or extracting device applied thereto for use. To lower the derrick to the position shown in full lines in Fig. 2, the free end of the line is also attached to the fixture 24 and sufficient slack in the line allowed to permit the derrick to be pushed by hand backward beyond the perpendicular, so that it will swing by gravity to lowered position, its movement to such position being controlled by means of the band-brake. When the derrick is lowered, the apparatus may be tilted to a horizontal position by pulling down upon the top or free end of the derrick and a draft attachment suitably applied to said top end of the derrick to enable the device to be transported on the wheeled truckframe 1.

The parts are so constructed and proportioned that the weight of the frame, reel, and base portion of the derrick will be slightly greater than the upper portion thereof, which projects beyond the cross-bar 3 when the derrick is in lowered position, so that while the greater weight of the frame and base portion will elevate the top end of the derrick when the latter is detached from the draft-animals 8o 7 the parts will be so nearly balanced as to render it easy for the draft-team to support and haul the apparatus. The pulley 22 is provided to enable more than one hoisting and lowering line to be employed when an unusually heavy part or a number of-parts are to be elevated or lowered.

By the use of the crank 30 and the brake and ratchet operating mechanism the action of the Windlass may be readily and conven- 9o iently controlled to slacken or tighten the line for disengaging and engaging the grapple or extracting device from or with the joint of tubing or part to be elevated or lowered, and

the descent of the line with the attached extracting device into the well may be readily controlled by the action of the brake on the Windlass. The ratchet mechanism further adapts the Windlass to be operated manually for removing parts or a string of tubing from a well in order to permit the grapple or ex tracting device to be detached from the tube.

It will thus be seen that the apparatus may be conveniently controlled in use, may be operated manually or by horse or other power, and may also be conveniently transported from well to well for use. When the apparatus is set for operation, the weight of the derrick and load is supported by the baseblocks 7, and as the weight of the derrick is slightly more than counterbalanced by the weight of the truck-frame it will be understood that by the simple application of suitable guys or stays to the elevated derrick the latter will be firmly supported.

Having thus described the invention, what is claimed as new is 1. In an apparatus of the character described, the combination of a wheeled truck, a base, connections between the truck and base and forming therewith a supportingframe, a derrick pivotally mounted upon the base and adapted when raised to be supported by the base and frame and when lowered to rest upon the truck, and hoisting means mounted upon the derrick.
